.The forward end of the bracket 16 is forked,

as clearly seen in Fig. '2, and constitutes a guide for l-ateralmovement of a frame 21 rigidly secured to thetongue 20, said frame 21 hereinafter referred to as the tongue frame is rounded at the rear end where it engagessaid bracket 16 and has also rounded sides to: have relative movement'to the side bars 11 of the Wheel frame as hereinafter explained. The tongue frame 21 includes'a plate 22-secured to saidframe at the forward end and having flanges 22 between which the tongue 20 is received. Bolts 23 secure to the tongue upper and lower strap irons 2%, 25 and the rear ends offthe straps are bolted as at 27 to a cross brace 26,

i the ends of which are secured as at28 to the sides of the tongue frame 21. Also said plate 22 of tongue frame 21 has aboss 21 through which one of thebolts 23 passes. In addition to the cross brace 26 there is a curved brace 29 in the tongue frame 21,- said curved brace being formed in sections that overlap and are secured by a'bolt 30 to the rear end of the tongue 20. The sections of the brace 29 curve rearwa rdly and carry shoes 31 which are grooved rto receive the tongue frame 21, while permitting adjustment of said shoes on the frame as hereinafter explained. Bolts 32 extend through the cross brace 26 near the ends andth'rough the members of the curved brace 29adj acent to the shoes 31 and in order that there may be relative adjustment of these parts with amovement of the shoes 31 on the tongue frame2l, a series of holes 33 are formed in 1 thebrace members 29 and a series of holes 35L in thecross brace 26. Bolts as at3l may be employedto secure the shoes 31 inthe adjusted position although it will be observed that they curved braces 29 definitely position the-said shoes according to the ad,-

justment of'the-said; braces. 1 When bolts are employed at 31 a series ofholes in the tongue frame 21 accommodate the bolts in the adjusted positionQ 7 v The'-structure 17 carryingthe seat 18" is in the; formof an arch having a base 35 securedby the pivot bolt 19 to the casting 16, as we'll as side uprights 36 and a top cross bar 37. Connection is established between the tongue and the structure 17 as follows: Cross braces or links 38 connect the base bar 35 with the cross bar 26 of the tongue frame 21 and cross links or braces 39 connect the top bar 37 with said cross bar 26. The forward ends of the bars 38, 39 extend, respectively, to the upper and lower sides of the cross bar 26 and aresecured to said bar and to one another as at 40 to, permit of pivotal play.

Similarly, the rear ends of the cross bars 38 are bolted as at 4:1 to the base bar 35 and the rear ends l3 of'the cross brace 39 are hooked to extend through holes in the bar 37and threaded to receive securing nuts The connection between the said structure 17-and the tongue frame 21 through the medium of the cross bars 38, 39 serves to give a lateral throw to the tongue 20 and its frame 21 by a movement of the seat about the pivot 19-as will hereinafter more and the movement of the wheel frame 10 by thesaid tongue frame may best be under stood after considering the floating plow structure carrying the cultivator shovels or plowsas next described.

The plow beams 46 carrying plows or shovels 47in suitable numbers and positions are connected at their forward ends with a transversefloating arch designated generally by-thenumeral 48, each lower laterally offset :end'l49'of which has fitted thereon-a sleeve 50'concaved at'its ends to correspond withcone bearings 51, 52. To the upwardly projecting ends of the bearings 51, 52a horizontal strap 53 is secured,.said strapbe ing bent around the vertical portions of the arch 48 and extending outwardly therefrom to receive-between the opposite sides of the strap the projecting ends of the bearings.

The outer bearing 51 issecured by a slot and v pin-connection, "there being a slot 54; in the strap receiving a pin 55 extending through said slot and through the upwardly projecting def, said bearing 51. At the opposite end: each strapc53 is'secured by-a pin 55 passing through holes iii-the opposite sides ofthe strap; The slot and pin connection 5 land 55'provides for the adjustment of the bearings 51, 52 against the sleeve 50 for tak- 3O 7 T (Yo each-sleeve BOiissecfired-a cl'a'n p 64 by wardly bent rear end secured in one of a clamps 6%, a1'1d;the"pi'ovision of the b'raee i ng "up Wear.

I I

It is to be observed that the tongue structure including the tongue proper 20 and the frame 21 is a floating structure, the same beingfree to float laterally by a sliding movement on the wheeled frame, since it has no pivotal connection or other positive connection orrestraint on the wheeled frame. The only restraint to the lateral floating movement of the tongue frame is the connection of the front end' with the draft animals and the lateral movement being limited by the sidemembers of the wheeled frame.

The movements of the parts in guiding the cultivator are as follows, reference being had to the diagrammatic Figs. 11 and 12 in addition to theother figures showing the detail construction described. In order to guide the plows to the left, for example, in maintaining the plows in proper positions relatively to the row of plants, the driver pressing his foot against the left foot bar ll lwill swing'the seat to the right, saidseat turning with the pivot 19 as a center. This will cause the cross bars 38, 39 to swing the tongue with its frame 21 to the left. The frame 21 in turn in contacting with the adjacent side bar 11 of the wheel frame at the guide bracket 15 will move the wheel frame to the left, thereby castering thewheels. In the movement of the floating tongue frame to the left the tongue as a whole will have more or less movement in the same direction,

the forward end tending to swing on the neck yoke connection and to whatever extent the neck yoke connection fails to hold the 45 tongue will have guiding movement on the horses in the proper directlon.

tongue then the lateral movement of the v Since the tongue frame is floating in the wheel frame and the point of contact isat the bracket 45, the forward end of the wheel frame 10 will have faster movement than the adjacent portion of the tongue, the tongue frame and wheel frame changing their relative angularity, in which movement the tongue frame 21 may race in the guidebrackets 45. The accelerated movement of the front end of the frame, thus quickens the lateral movement of the floating plow structure in dodging a plant or obstruction. In the lateral movement of the front angle bar of the wheel frame 10 it will swing the floating arch 48'tothe left by the connection due to the hanger rods 56, theneby giving to the lateral movement imparted to the wheel frame in addition to the positive movement of the floating plow structure by the direct pressure of the. drivers foot. The .whole floating plow structure being stiflened by the braces 71 and clamps 64:, the right plow beam respondsto the movement of the left plow beam. An accelerated lateral movement of the floating plow structure is further produced by the fact that the lever 108 partakes of the movement of the bracket 111 on the wheeled frame which therefore bodily carries the lever 108 faster than the link 112 is moved by the tongue frame 21, the result of which is that therelatively slower speed of the link 112 holds back the adjacent arm of the lever 108, thereby relatively increasing the throw of the opposite arm and causing the link 113 toincrease the movement of the floating arch relatively to the tongue structure. In the lateral movement of the parts to the left also, the rods 62 play a part. As will be seen from the plan view these rods are'somewhat convergent toward the front and the front ends of said rods 62 move faster than the rear ends, the front end of the rod '62 at the left swinging forwardly in an arc while the front end of the right hand rod 62 swings rearwardly in an arc, the result of which will be a tendency to retard the forward movement of the right hand plow beam 46 while the left hand rod 62 exerts a forward thrust on the floating arch 48 and thereby tends toexert a forward pull on the left hand plow beam 46, thus contributing to the guided movement of the plows. We have thus seen that all the movements contribute to quick and effective guiding of the plows, due, first, to the direct thrust on the floating plow structure by the driver; secondly by the lateral movement of the tongue and its guiding eflect on the horses; third, the castering movement of the wheeled frame; and fourth, the accelerated movement of the floating plow structure at the front in the proper direction. In any lateral guiding action on the horses by the swinging of the tongue a further contribution is given to the guided movements by the pull of the, horses through the draft trees on the ends of the floating arch through the connection with the chains 17. The angularity of the rods 62 is variable by shifting the shoes 31, and the adjustment of the same and of the curved brace sections 29 by engaging the pin 32 in one or other of-the holes 33, 34:, said brace sections 29 being adapted to pivot on the securing bolt 30.

Referring again to the adaptability of the bracket 111 and the lever 108 to receive either fulcrum pin 109 or 110, it is explained that with both of said pins in place, obviously no action of the lever is possible and this condition is produced when the cultia 55 their angular relation in responseto-pres- 'vait'or not :actionias; Whenqgoing' to or parture l'from :the spirit :of theiinvention as =de finedrin the appendedolaims.
